Possum Ripple Hat. A recent addition to our collection - more feminine - this is fast becoming an urban classic! Yet still extraordinarily practical. Why not combine it with a matching scarf - either separately or as part of a bundle at discount? For a touch of style it is hard to beat Koru's Ripple Hat. Designed to be worn when you need to feel a bit special it is made from 40% Possum, 50% Merino Lamb’s Wool, and 10% Silk.
